1. A tool and die maker is reviewing a blueprint for a progressive die. Which document should
be consulted first to verify dimensional tolerances?
A. Material safety data sheet
B. Maintenance log
C. Engineering drawing
D. Shipping manifest
════════════════════
Correct Answer: C. Engineering drawing
Rationale:
The engineering drawing contains the specified dimensions, tolerances, and design
requirements needed for accurate die construction. The other documents do not provide
dimensional control information.
════════════════════
2. Which measuring instrument is most appropriate for checking the outside diameter of a
precision punch to within 0.0001 inch?
A. Steel rule
B. Outside micrometer
C. Tape measure
D. Combination square
════════════════════
Correct Answer: B. Outside micrometer
Rationale:
An outside micrometer provides the precision necessary for extremely accurate diameter
measurements. The other tools lack the required accuracy.
════════════════════
,3. During die assembly, a component repeatedly binds during movement. What should be
checked first?
A. Alignment of mating components
B. Paint condition
C. Shipping records
D. Tool storage location
════════════════════
Correct Answer: A. Alignment of mating components
Rationale:
Misalignment is a common cause of binding and should be investigated before more complex
troubleshooting steps.
════════════════════
4. What is the primary purpose of heat treating tool steel?
A. Improve appearance
B. Increase hardness and wear resistance
C. Reduce dimensions
D. Increase conductivity
════════════════════
Correct Answer: B. Increase hardness and wear resistance
Rationale:
Heat treatment enhances hardness, durability, and wear resistance, making the tool suitable
for production environments.
════════════════════
5. A journeyman notices burrs on stamped parts. Which die condition is the most likely cause?
A. Excessive lubrication
B. Sharp cutting edges
C. Dull cutting edges
,D. Excessive polishing
════════════════════
Correct Answer: C. Dull cutting edges
Rationale:
Dull cutting edges tend to tear material instead of shearing it cleanly, resulting in burr
formation.
════════════════════
6. Which safety practice is most important before servicing a press?
A. Clean the floor
B. Verify production count
C. Lockout/tagout energy sources
D. Check shipping schedules
════════════════════
Correct Answer: C. Lockout/tagout energy sources
Rationale:
Lockout/tagout procedures prevent unexpected machine startup and protect workers from
serious injury.
════════════════════
7. What is the primary function of a die set?
A. Increase electrical power
B. Support and align die components
C. Store spare parts
D. Measure stock thickness
════════════════════
Correct Answer: B. Support and align die components
Rationale:
The die set maintains alignment between upper and lower die sections, ensuring consistent
operation.
, ════════════════════
8. Which machining operation is commonly used to create highly accurate flat surfaces?
A. Grinding
B. Sawing
C. Drilling
D. Casting
════════════════════
Correct Answer: A. Grinding
Rationale:
Surface grinding produces precise, flat finishes required for many tool and die applications.
════════════════════
9. When reading a blueprint, what does a geometric tolerance primarily control?
A. Material cost
B. Part packaging
C. Shape, orientation, or location
D. Production scheduling
════════════════════
Correct Answer: C. Shape, orientation, or location
Rationale:
Geometric dimensioning and tolerancing defines allowable variation in part geometry and
relationships.
════════════════════
10. Which material property is most critical for a blanking punch subjected to repeated
impacts?
A. Color
B. Toughness
C. Transparency
